By modified agar method,the induced polyploid breeding of Ailanthus altissima（Mill.） swingle was carried with adding 0.2% colchicine solution into 1.0% agar solution for 24 h,48 h,72 h,respectively,which induction rates were 61.90%,62.07%,46.88%.According to morphological characteristics of polyploid,the biology characteristics of induced mutation were significantly related with the control.
